(CNN) – Acetaminophen is supposed to be the safe option; most widely known as Tylenol, the drug is routinely prescribed by doctors for pregnant women in pain.

But a new large study out of Denmark calls this long-standing practice into question, finding that women using the common pain reliever during pregnancy are more likely to have children who go on to have ADHD.FULL POST

For 15 years, Viagra has been a champion for its creator Pfizer; the little blue earned $2 billion dollars last year.

That got a rise out of the competition, and now there is a whole sub genre of Viagra copycat drugs.

It's been so successful, the movie "Love and Other Drugs" immortalized the Viagra salesman.

"Men without a useful erection for years. Boing! Minimum side effects. Long-term safety. This isn't a pill. This is a revolution," said the movie's character Jamie Randall, portrayed by actor Jake Gyllenhaal.
